Application filed April 23, 1915. Serial No. 23,429.

To all whom it may concern:

Be it known that 1, JOHN S. ALDEN, a citizen of the United States, residing at Van, in the county of Venango and State of Pennsylvania, have invented a new and useful Safety-Envelop, of which the following is a specification.

The present invention appertains to envelops, and aims to provide a safety envelop of novel and improved construction, and adapted for the transmission of money or other valuables therein Without the liability of the contents being removed without destroying or so mutilating the envelop that.

the tampering can be detected.

It is the object of the invention to provide a blank which when folded and pasted provices a safety envelop of thoroughly efficient yet simple and inexpensive construction.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is a plan view of the blank from which the envelop is formed. Fig. 2 is a back view of the envelop in sealed condition. Fig. 3 is a longitudinal section of the envelop taken on the line 3-3 of Fig. 2.

The blank, which may be cut from suitable paper, cloth, or other material, embodies a rectangular body 1 which later forms the front side of the envelop, and which is provided at its edges with flaps 2 each provided with a longitudinal series of lateral slots 3. The body 1 is provided at one end with a closure flap 4 having a slot 5 therein adjacent its free edge. and the body 1 is provided at the other end with a flap 6 having a tongue 7 projecting longitudinally from its free edge. The tongue 7 has a tab 8 at its free end.

In folding the blank to form the envelop, the flaps 2 are folded one over the other, so that the slots 3 aline or register with one another, and the tongue or flap 7 is then threaded inwardly and outwardly through the slots 3, so that the tongue 7 literally sews the flaps 2 together. The flap 6 overlaps the outer sides of the adjacent ends of the flaps 2, and the free portion of the tongue 7 projects from the flaps 2 adjacent the closure flap l of the envelop. The parts 2, 6 and 7 are pasted or otherwise secured together, and the envelop is then in condition to receive the money or other valuables.

When the envelop is filled, the free portion of the tongue or strap 7 is inserted outwardly through the slot 5 of the closure flap 4-, and the closure flap is then swung against the outer side of the back of the envelop formed'by the overlapped portions or flaps 2, the tab 8 then being bent back over the front side of the envelop. An eyelet or other securing element 9 is then engaged through the tab 8, and the body portion of the tongue 7, and penetrates the flap 4, flaps 2, and front side of the envelop, whereby the parts are securely fastened together, to prevent the tongue 7 or flap f from being loosened without destroying or mutilating the envelop. The flaps 2 and 6 cannot be loosened without tearing the envelop, and it is thus impossible for a maliciously inclined person to open the envelop and remove the con tents, without tearing or destroying the envelop, so that the tampering would be noticed.

The present envelop may be employed for mailing different valuables orrmessages, and is adapted for use for various purposes as will be obvious.

Having thus described the invention, what 90 is claimed as new is:

An envelop having overlapped portions provided with registering slots, a closure flap provided with 'a slot. and an opposite flap having a tongue projecting therefrom. said flaps overlapping the outer sides of said portions, the tongue being threaded inwardly and outwardly through said registering slots, the'free portion ofthe tongue Q In testimony that I claim the foregoing as being inserted outwardly through the slot: my own, I have hereto, aiiixed my signature of the closure flap, and the tongue having a in the presence of two Witnesses.
